Implementation of LOGIC GATE
Aim of the Experiment :
Implementation of LOGIC GATE
Minimum Requirements :
9V battery or power supply
Voltage Regulator (7805)
330Ω, Two 1kΩ resistors
BC547 Transistors
Switches
LED
Connecting wires
Working Principle :
For building an AND logic gate using a transistor we would be using BJT transistors. The circuit would make the LED glow i.e. the output is 1 (High) only when both the inputs are 1 (High) i.e. when there is a voltage supply at the base terminal of both the transistors. Meaning, there will be a straight line current path from VCC (+5V power supply) to the LED and further to the ground. Rest in all the cases, the output will be 0 (Low) and the LED will be OFF.
